<p>An air turbine starter system and air turbine starter valve that has a microvolume actuator to prevent the connected butterfly valve from opening too quickly. Air turbine starter valves can in some circumstances freeze shut, but may be opened by normal actuator operation. Such operation may open the valve too quickly due to stored potential energy. A sharp pressure transient may be inflicted upon the connected air turbine starter which can cause damage. The microvolume actuator air turbine starter system set forth herein allows generation of sufficient force to break ice and move the valve while minimizing stored potential energy that could open the valve too quickly.</p>
